X-Ray images of women wearing corsets from French doctor Ludovic O'Followell's Le Corset (1908). Although keen to show the damaging impact of corsets, he did not actually want the corset to be abolished, but simply redesigned: https://publicdomainreview.org/collection/the-corset-x-rays-of-dr-ludovic-o-followell-1908
@publicdomainrev It is fascinating that in the early 1800s, women were wearing empire dresses that didn’t emphasize their waists, but by 1830, they were back in dresses that did, with wasp-waisted corsets. I have no idea whether this was precipitated by the invention of the metal eyelet right around that time (as mentioned in the article), but it sure is an interesting coincidence.
